All the particles that make up the matter around us, such electrons and protons, have antimatter versions which are nearly identical, but with mirrored properties such as the opposite electric charge.
Antimatter may exist in relatively large amounts in far-away galaxies due to cosmic inflation in the primordial time of the universe. Antimatter galaxies, if they exist, are expected to have the same chemistry and absorption and emission spectra as normal-matter galaxies, and their astronomical objects would be observationally identical, making ...
In physical cosmology, the baryon asymmetry problem, also known as the matter asymmetry problem or the matter–antimatter asymmetry problem, [1] [2] is the observed imbalance in baryonic matter (the type of matter experienced in everyday life) and antibaryonic matter in the observable universe.
In physical cosmology, baryogenesis (also known as baryosynthesis [1] [2]) is the physical process that is hypothesized to have taken place during the early universe to produce baryonic asymmetry, i.e. the imbalance of matter and antimatter (antibaryons) in the observed universe.
As with the majority of his own Antimatter recordings, Moss elected to perform the core instruments of guitars, bass, synths and e-bows himself. [6] Guest musicians were drafted in the form of Fab Regmann (drums), Carla Lewis (vocals), Julie Rodaway (flute), Paul Thomas (saxophone) and Vardan Baghdasaryan ( kamancheh ).
Antimatter – Material composed of antiparticles of the corresponding particles of ordinary matter; Dark energy – Energy driving the accelerated expansion of the universe; Dark matter – Concept in cosmology; Gravitational interaction of antimatter – Theory of gravity on antimatter; Mirror matter – Hypothetical counterpart to ordinary ...
A graphic representation of Wheeler's calculations of what quantum reality may look like at the Planck length. Quantum foam (or spacetime foam, or spacetime bubble) is a theoretical quantum fluctuation of spacetime on very small scales due to quantum mechanics.
The universe is composed almost completely of dark energy, dark matter, and ordinary matter. Other contents are electromagnetic radiation (estimated to constitute from 0.005% to close to 0.01% of the total mass–energy of the universe) and antimatter. [91] [92] [93]
